17.5-inch Radiator for 1964-1967 Pontiac GTO A-Body LS and LT Engines
If you're planning an LS or LT engine swap into a 1964 to 1967 Pontiac GTO A Body, the 1964 through 1967 GTO Radiator 17.5" tall (Manual Trans) is designed to preserve factory coolant routing and fan shroud alignment without any trimming. With its 17.5-inch core height and precise port spacing, this aluminum radiator drops into the original frame rails, matching the factory 17.5" tall core. Offered in bare aluminum or black epoxy coating, it resists corrosion and maintains optimal heat rejection. Fully assembled in the USA, each unit includes one radiator ready for manual transmission installations.
Precision Fitment for Classic GTO
This radiator is engineered specifically for 1964 through 1967 GTO models equipped with manual transmissions. The core measures 17.5 inches tall, matching the original factory dimensions to maintain correct positioning within the chassis. Integration with MuscleRods mounts ensures that the engine sits at the factory angle, optimizing driveline alignment and preventing undue stress on couplings. This direct installation eliminates the need for alterations to the frame or support brackets, preserving the vehicle's heritage while guaranteeing reliable coolant flow.
Advanced Thermal Performance
Constructed from high-quality aluminum, this radiator delivers superior heat dissipation compared to stock units. Its precision tube and fin arrangement maximizes air contact and coolant circulation, reducing operating temperatures under sustained load. During spirited driving or heavy traffic, efficient heat exchange prevents boil over and maintains consistent thermal stability. By minimizing temperature spikes, the upgraded core safeguards critical engine components and enhances overall cooling capacity for both LS and LT powerplants.
Constructed in the USA for Enduring Quality
Manufactured domestically, each radiator undergoes comprehensive pressure testing to verify seal integrity and leak free operation before shipping. By keeping production local, customer demands are met quickly while supporting regional industry standards. Rigorous quality control ensures resistance to corrosion and a long service life in diverse environments. This combination of reliable performance and precise engineering provides classic GTO enthusiasts with confidence in every mile, backed by American craftsmanship.
